Abstract
The invention relates to a method and device for detecting and localizing diffuse-reflecting coatings situated on a translucent pane. The aim of the invention is to make it possible to detect any diffuse-reflecting coatings in a non-contacting manner and to differentiate between coatings situated on the pane surface facing the sensor and those situated on the pane surface facing away from the sensor. To this end an image of an object is captured by a recording unit forming part of the device by positioning the pane in the optical path between the object and recording unit, after which the image information obtained is evaluated accordingly.
